The purpose of this study were to conduct and to evaluate the effectiveness of Automotive service technician The research procedure starting by collect and study document : research paper international occupational standard (Oklahoma Department of Career and Technology Education) and competency needed in Motorcycle Mechanic suggested by 7 person who working in this field. All data will be referred for behavior objectives list and learning materials design such as information sheet practice operation sheet for experience skill training evaluation sheet with evaluation criteria which clearly listed topics. The sample group in this study was 19 PAJAMANGALA UNIVERSITY OF TECHNOLOGY PHRANAKHON Faculty of Industrial Education in academic year 2 0 1 7 . Pre-test will be given before training steps according to the manual. The students will do the test after each training topic. At the training end Post-test will be given and student final assignment will be evaluated by 5 experts. The Pre-test and Post-test scores will be statistical mean difference test. The research results found that the student final assignment competencies evaluation in percentage mean score was 87.55/94.66/85.13 that higher than 80/80/80 about the expectation. The test percentage mean score after training each topic was 92.11 that higher than 90 about the expectation. The percentage mean score difference test between before and after training was significant at statistical level .01 and the after training score was higher than before training score.

This research aims to develop the coconut coir ceiling board mixed with natural latex. The 6 ratios of gypsum plaster: coconut coir: sodium silicate: natural rubber: tap water are equal to 1: 0.15: 0.03: 0.00: 1 1: 0.15: 0.03: 0.01: 1 1: 0.15: 0.03: 0.02: 1 1: 0.15: 0.03: 0.03: 1 1: 0.15: 0.03: 0.04: 1 and 1: 0.15: 0.03: 0.05: 1 by weight. The ceiling boards were produced by casting in normal temperature (30 – 35 degree of Celsius). The properties testing of coconut coir ceiling board mixed with natural latex followed the TIS 219-2009 standard (gypsum plasterboard) including: breaking load nail pull resistance deflection water absorption density thermal conductivity coefficient and real usage. From the results 1: 0.15: 0.03: 0.03: 1 ratio is the most suitable ratio of coconut coir ceiling board mixed with natural latex. This developed ceiling boards can reduce the quantity of coconut coir waste and get the good thermal insulation ceiling board products.

The study of the development of gluten-free brownies with instant Stevia powder for partially replacing some amounts of sugar aims to (1) develop a brownie recipe by using gluten free flour (2) optimise the amount of the instant Stevia powder in order to replace some amounts of sugar partially within the brownies (3) compare the nutrition facts between conventional brownies and the gluten-free brownies with stevia for replacing some amounts of sugar and (4) investigate the consumer perception on the developed recipe. The result shows that the conventional brownies had a higher overall linking based an 9-Points hedonic scale than those of of the samples substituted with Red brown hom mali rice flour. The conventional brownies which consist of Red brown hom mali rice flour and corn flour with a ratio of 50:50 gain higher than the other recipes with a ratio of 60:40 and 70:30. In addition the result of utilising stevia to replace some amount of sugar shows that a sweet ratio of 25:75 is the most favourable recipe than a ratio of 50:50 and 75:25 (p<0.05) For nutrition facts there was no statistically significant difference between the conventional brownies and the brownie added with instant stevia powder. the brownies added with instant stevia powder contains energy moisture fat protein carbohydrate and ash of 480.89 15.90 30.09 5.70 46.82 and 1.49 respectively. The consumer acceptance test using questionnaire in 100 ordinary consumers the result found that the respondents satisfied the instant stevia powder in order to replace some amounts of sugar partially within the brownies in aspect of the flavor of 62.58 the most and following by in aspect of the benefits for health of 58.09 with acceptance towards product was 100%.

Nowadays the measurement technologies are continually growth in advanced. These can be seen in the developed and developing countries that research and develop the products which support the consumer behavior and/or country economy ic growth. However some advanced products are very expensive such as pH meter. Therefore this thesis develops the pH meter which allows the acid-base test of the water and it can be supported the agriculture. The proposed pH meter is included the pH pen sensor temperature sensor water level sensor. The proposed meter can measure the acid-base of the water by sending SMS alert signal via GSM module to the mobile phone of the farmer. As can be seen this thesis can prevent and solve the effect of the high acid-base of the water that possibly flows into the agriculture farm via using SMS alert signal of the mobile phone of the farmer.

Energy is an important factor in the necessity of human life. Many countries around the world are seeking alternative energy sources. To use as alternative energy. Our alternative sources of energy are ethanol which can be produced from agricultural products. Including plants with cellulose components. The ethanol can be mixed with gasoline. It is a new product called gasohol. This research use of fresh water weed Hydrilla is a raw material in the production of ethanol. Hydrolysis sweetening and fermentation. The microorganisms used in fermentation processes the yeast is found Hydrilla through hydrolysis the acid is H2SO4 at 0.5 % . Measuring the concentration of the alcohol concentration of 4.0 % VOL 9 Brix %. The Hydrilla through hydrolysis at alkaline NaOH is at a concentration of 1 % concentration of alcohol concentration was 3.5% VOL 8 Brix %. Hydrilla and the Hydro Delight with distilled water (H2O) to measure the concentration of the alcohol concentration of 5.5 % VOL 12 Brix %. Thus it can be said that Hydrilla is a material that has the potential to produce ethanol for energy alternatives. And used as a source of renewable energy. Instead of using raw materials from food plants. And other energy crops.
